Arctic seafloor at 500 meters water depth. Carbonate blocks are colonized by anemones and sponges. Tube worms are abundant at the seafloor. In the upper part of the image, we see patches of bacterial mats. All of these features are indigenous to sites of methane release. Schools of codfish appeared to be following the laser beams from the camera system. Fish were often observed in big quantities during the cruise. CREDIT Courtesy of CAGE/UiT

More methane seeps discovered in the deep ocean

Over a course of 12 days Dr. Giuliana Panieri and her colleagues from Centre for Arctic Gas Hydrate, Environment and Climate (CAGE) collected images from seven areas of known methane release in the Arctic Ocean. One of them was Vestnesa Ridge, with over 1000 active seep sites at the depth of over 1000 m. Methane…

Abiotic methane discovered under the Arctic Ocean

From CAGE – Center for Arctic Gas Hydrate, Climate and Environment New source of methane discovered in the Arctic Ocean Methane, a highly effective greenhouse gas, is usually produced by decomposition of organic material, a complex process involving bacteria and microbes. But there is another type of methane that can appear under specific circumstances: Abiotic…
